Save Energy &
Protect The Environment
Following the trends and needs of the market, ECOTHERM
has created a new line of thermosiphonic solar water heaters,
called ECOLUTION. This brand new line will provide a
solution to modern demands for even more money saving
solar systems. By redesigning the product, ECOTHERM
managed to reduce the cost of the tanks whilst keeping the
same high quality.
The ECOLUTION tanks are entirely manufactured in Greece,
according to the European standard EN 12976. The metal
fixation supports of the same line have an identical production
philosophy as origin, while the new design has allowed
a reduction of the costs as well. The new metal fixation
supports are compatible with every tank model without any
special adjustment needed, apart from the 250 L and 300 L
tanks, where two extra holding parts are added because of
the great volume of the system.
